One of the neat things about Rolls-Royce is the extraordinary lengths the company will go to for maximum comfort. It's like how supercar builders will look for every little advantage to make their cars a tenth of a second faster. On the 2021 Rolls-Royce Ghost, the company is employing something called the Planar Suspension System, a nebulous designation for the collection of systems and parts employed. Some are straight forward, such as the four-wheel independent air suspension, and the way the GPS and forward cameras inform what level of firmness should be employed on the road. But one part left us perplexed: the upper control arm damper. We spoke to Jon Simms, lead engineer for the Ghost, for more information, and now we have a better grasp on what it is and what it does.

As for what it is, it's the roughly horseshoe-shaped object highlighted in purple in the above photo. The yellow parts are bumpstops, and it's mounted on the same joint as the upper control arm. And it turns out it's a pretty simple piece of equipment. It works very much like the harmonic balancer on the end of an engine. It's a weight with a rubber-y flexible hinge, and going over smaller bumps, it absorbs some of the extra vibration and movement from the suspension. Those bumpstops in yellow give the damper some extra purchase on the control arm, and they absorb impacts from larger bumps that may move the control arm suddenly so that the arm and damper don't bang into each other.

This may seem like a pretty minor thing, but remember, Rolls-Royce and its buyers are out for maximum comfort, so there's reason to invest in ironing out every possible ride quality issue, no matter the size. And even if it's a minor improvement, that's not necessarily a bad thing. Simms told us that existing Ghost customers they talked to during development had one key request about the driving experience: "don't break it." So making sure that the new car was basically like the last one, but a bit better, would seem to be what customers would want.

The Ghost is the first Rolls-Royce to adopt this full suite of Planar Suspension System parts, though other Rolls-Royce models have had pieces of the system. And considering the fact the Ghost shares its platform with the Phantom and Cullinan, now, we wouldn't be surprised if later versions of those models pick-up parts like this damper.

Rolls-Royce made the second-generation Ghost about 3.5 inches longer than its predecessor. If that's not enough, the British firm just unveiled a long-wheelbase variant named Extended that gains another seven inches.

Company boss Torsten Müller-Ötvös explained the Ghost Extended was developed for customers who want to be driven during the week, but who prefer to drive themselves on the weekend. His team's challenge was to carve out more space for the rear passengers without compromising the sedan's handling, or significantly altering its proportions. To that end, stylists extended only the rear doors and the sheetmetal around them.

Rolls-Royce hasn't released images of the front part of the cabin; it's what's out back that counts. Business-class-like individual Serenity Seats are offered at an extra cost (even the ultra-rich have to tick option boxes), and the BMW-owned company proudly noted it allocated a spectacular amount of resources to developing the perfect in-car champagne cooler. Nestled between the rear seats, it has two operating modes: it chills non-vintage champagne to precisely 6 degrees Celsius, and vintage champagne to exactly 11 degrees.

Rear-seat passengers can sit back, sip Dom Pérignon Rosé that costs as much as a Nissan Sentra, and enjoy more legroom than many people have in their living room. Only the Phantom Extended offers a more spacious cabin, the firm claims. Alternatively, they can work on-the-move thanks in part to the in-car Wi-Fi hotspot.

Rolls-Royce made no mechanical changes, meaning the Extended uses the same 6.75-liter V12 as the standard-wheelbase model. It's twin-turbocharged to 563 horsepower and 627 pound-feet of torque, and it spins the four wheels via an eight-speed automatic transmission. All-wheel steering comes standard, and one of the most advanced suspension systems in the world ensures the Ghost delivers the Magic Carpet Ride buyers expect.

Ghost Extended deliveries will begin during the fourth quarter of 2020. Rolls-Royce hasn't announced pricing information, but the sedan likely costs over $350,000 before options — and champagne — are factored in.
